I don’t know where the mercury would sit to make the lower back hurt, but for me it is “muscle weakness” and the muscle weakness causes my back to hurt. My spine does not have enough strength to keep it in the right shape/position, which is different to mercury actually sitting somewhere on my lower back. I think (guess) that the mercury is sitting somewhere that causes my muscles to work incorrectly…..i think(guess) that the mercury is sitting on my brain, as the brain controls the muscles and how they work.

I have not seen it written anywhere exactly like that, but that’s my understanding anyway from the reading I have done and from all my experiments.

Cutler does talk about muscle weakness being a common problem …..it was a one liner somewhere in AI.
